I will be praying for you. Just by you realizing your need for Christ, you have made the first step. Now you just have to surrender your life to him and accept him as your lord and savior. The bible speaks of repenting of our sins, and contrary to what people think, repent doesnt mean confess or say that you are sorry for them. To repent means to turn away from something. So acording to the word of God we are to turn away from our sinful ways and turn toward new life in Christ.
By realizing that you are a sinner, confessing those sins and asking forgiveness for them, is the first step. Repenting of the old life and asking him to be your Lord and Savior is the next. there are no magic words, its just between you and God. I will be praying for you.
